10 Common Presentation Mistakes

Often, the sorts of problems that can jeopardize your presentation will be situations beyond your control, but this doesn't mean that you're helpless. Conduct a risk analysis to identify potential issues, and come up with a good "Plan B" for each one.

Mistake 3: Ignoring Your Audience

Sometimes, speakers can get so wrapped up in delivering their presentations that they forget about the needs of their audience.

Start your presentation by telling your audience what to expect. Let them know what you'll cover first, whether and when you'll stop for a break, if you'll be taking questions during the presentation, and so on.

Providing these "signposts" up front will give your audience a clear idea of what to expect, so that they can relax and concentrate on your presentation.

Mistake 4: Using Inappropriate Content

The primary purpose of any presentation is to share information with others, so it's important to consider the level you'll pitch it at.

Do some research on your audience. Why are they here? How much do they already know about your topic, and what do they most want to learn from you? It's no use giving a presentation that's so full of jargon that no one understands you. But you wouldn't want to patronize people, either.

Try to put yourself in people's shoes, to get a clearer idea about their needs and motivations. You can also greet individuals as they arrive on the day, and ask questions to get a feel for their level of knowledge. This will also help you to personalize your presentation and make a connection with each person in your audience, so that they'll be more attentive to what you say.

Mistake 5: Being Too Verbose

Short, concise presentations are often more powerful than verbose ones. Try to limit yourself to a few main points. If you take too long getting to your point, you risk losing your audience's attention.

The average adult has a 15- to 20-minute attention span. So, if you want to keep your audience engaged, stick to the point! During the planning phase, make a note of the themes you want to cover and how you want to get them across. Then, when you start filling out the details, ask yourself: "Does my audience really need to know this?"

Mistake 6: Using Ineffective Visuals

Poor slides can spoil a good presentation, so it's worth spending time getting yours right.

We've all seen slides with garish colors, unnecessary animation, or fonts that are too small to read. The most effective presentation visuals aren't flashy – they're concise and consistent.

When choosing colors, think about where the presentation will take place. A dark background with light or white text works best in dark rooms, while a white background with dark text is easier to see in a brightly lit room.

Choose your pictures carefully, too. High-quality graphics can clarify complex information and lift an otherwise plain screen, but low-quality images can make your presentation appear unprofessional. Unless an image is contributing something, embrace the negative space – less clutter means greater understanding. Use animation sparingly, too – a dancing logo or emoji will only distract your audience.

Mistake 7: Overcrowding Text

The best rule of thumb for text is to keep it simple. Don't try to cram too much information into your slides. Aim for a maximum of three to four words within each bullet point, and no more than three bullets per slide.

This doesn't mean that you should spread your content over dozens of slides. Limit yourself to 10 slides or fewer for a 30-minute presentation. Look at each slide, story or graph carefully. Ask yourself what it adds to the presentation, and remove it if it isn't important.

Mistake 8: Speaking Incoherently

Even though we spend a significant part of the day talking to one another, speaking to an audience is a surprisingly difficult skill, and it's one that we need to practice.

If nerves make you rush through a presentation, your audience could miss your most important points. Use centering or deep breathing techniques to suppress the urge to rush. If you do begin to babble, take a moment to collect yourself. Breathe deeply, and enunciate each word clearly, while you focus on speaking more slowly.

One useful technique is storytelling – stories can be powerful tools for inspiring and engaging others.

Mistake 9: Showing a Lack of Dynamism

Another common mistake is to freeze in one spot for the duration of your presentation.

Some presenters feel most comfortable behind the podium. Try to emulate great speakers like Steve Jobs, who moved purposefully around the stage during his presentations.

As well as working the stage, he used gestures and body language to communicate his excitement and passion for his subject. Pay attention to what your hands are doing – they're important for communicating emotion. But only use gestures if they feel natural, and avoid being too flamboyant with your arms, unless you want to make your audience laugh!

Mistake 10: Avoiding Eye Contact

Have you ever been to a presentation where the speaker spent all of their time looking at their notes, the screen, the floor, or even at the ceiling? How did this make you feel?

Meeting a person's gaze establishes a personal connection, and even a quick glance can keep people engaged. If your audience is small enough, try to make eye contact with each individual at least once.

If the audience is too large for this, try looking at people's foreheads. The individual may not interpret it as eye contact, but those sitting around them will.
